Reconstructing Orbits of Galaxies in Extreme Regions (ROGER) II: reliability of projected phase-space in our understanding of galaxy populations
Valeria Coenda, Martín de los Rios, Hernán Muriel +4
We connect galaxy properties with their orbital classification by analysing a sample of galaxies with stellar mass residing in and around mas…
On the environmental influence of groups and clusters of galaxies beyond the virial radius: Galactic conformity at few Mpc scales
Ivan Lacerna, Facundo Rodriguez, Antonio D. Montero-Dorta +6
The environment within dark matter haloes can quench the star formation of galaxies. However, environmental effects beyond the virial radius of haloes ( 1 Mpc) are less ev…
Imprints of the cosmic void evolution on the baryon processes inside galaxy haloes
Agustín M. Rodríguez Medrano, Dante J. Paz, Federico A. Stasyszyn +1
Cosmic voids provide a unique environment to study galaxy formation and evolution. In this paper, we analyse a set of hydrodynamic zoom-in simulations of voids, to analyse in detai…
Evolution mapping: a new approach to describe matter clustering in the non-linear regime
Ariel G. Sanchez, Andrés N. Ruiz, Jenny Gonzalez Jara +1
We present a new approach to describe statistics of the non-linear matter density field that exploits a degeneracy in the impact of different cosmological parameters on the linear…
Redshift-space effects in voids and their impact on cosmological tests. Part II: the void-galaxy cross-correlation function
Carlos M. Correa, Dante J. Paz, Nelson D. Padilla +3
This is the second part of a thorough investigation of the redshift-space effects that affect void properties and the impact they have on cosmological tests. Here, we focus on the…
Galaxy populations in haloes in high-density environments
Ignacio G. Alfaro, Andres N. Ruiz, Heliana E. Luparello +2
There are hints suggesting that properties of galaxy populations in dark matter haloes may depend on their large-scale environment. Recent works point out that very low-density env…
Overdensity of VVV galaxies behind the Galactic bulge
Daniela Galdeano, Luis Pereyra, Fernanda Duplancic +7
We studied a region of 1.636 square degrees corresponding to the VVV tile . Using SExtractor, we analysed photometric data generating a catalogue of extended sources in this…
